Once "criminals" have a bright future and a job, they probably won't be criminals any more. I think that's a good thing for everyone involved.
I say "criminals" not to imply that what these people do isn't criminal (it is), but because dividing the world into criminals and good law abiding citizens is a false dichotomy. Normal people sometimes do criminal things and criminals sometimes to things that are good.
Additionally, by applying only the label "criminal" to certain people, you're ignoring that these are human beings with lives and dreams and ideas and problems and families, who have reasons for the things they do. They may be good reasons, they might not be, but to disregard them altogether is a mistake.
At the same time, you're implying that crime is a problem that either cannot be solved or can be solved by jailtime and harsh sentencing. Neither of these implications are true.
